So, if the mute switch on your device isn’t in the wrong position, it most likely is because it dosn’t control the sound anymore and now control the auto rotation. And if it was muted when you changed the functionallity, then sounds are still muted no matter what you do.

• How To Fix

Go to Settings/General/Use Side Switch to: set it to “Mute” and use the side switch on the iPad to turn the volume up.

You can then switch it back to “Lock Rotation” and ProChords will still play sound.

Important knowledge about sound on iOS devices.

It’s very important to understand that iOS devices have several different sound systems. ProChords use the same that most game developers use for making sound effects in their games, and NOT the one that i.e iTunes or Spotify uses to play music.

The sound effects system can easily be disabled, while the music system can’t.

Do the following check to find out if ProChords is the actual problem: Open a game like Angry Birds. If the birds are silent – it’s a settings issue.
